As a book reader, this episode left me so confused. Nearly everything was new and that ending gave information not even in the books. Honestly haven't enjoyed an episode of game of thrones this much since the first season

I agree. Even with big episodes such as Blackwater or the Red Wedding, despite their quality, they did not have that emotion punch it had for the show watchers. Tonight's ending felt like a roller coaster ride compared to the others. I hope we can have a few other similar episodes going forward, especially with ADWD coming into play.

I spent most of the episode kind of...mad. Which is to be expected from a book reader, at least on some level.

When it was over, and the credits began to roll, I literally said "What the fuck? Fuck them." Then all of the repercussions of what I saw started spilling into my head. Everything started rolling around, and suddenly, it wasn't "fuck them." It was "Jesus fucking christ. This means so much...."

And then I didn't sleep, stayed up all night (literally) putting together theories and thoughts and collecting myself. Hell, this morning, I'm still kin a daze, trying to make sense of it.

If this is how watchers feel, I wish I could go back and unread the series, to be honest. It's such a great feeling.

Eh, I just don't see what there is to get upset about. George R.R. Martin as well as the show producers have said going into this season that the show canon and book canon are going not going to sync well from this point forward. It would be too difficult given the budget, format, and time restraints. It occurs with basically every adaptation that transitions from book to screen.

As far as the reveal, I am just glad to finally see what lies that far north of the Wall. I don't mind learning new content before the release of the books. I read The Winds of Winter chapters when they are revealed, so having a few spoilers or plot points revealed does not bother me at all. If anything, it just gets me excited.

No, it's that he is this guy. He is a former Lord Commander of the Night's Watch. I don't see how it is an "insane spoiler" as the OP claims though. The Night's King was talked about in a season 2 featurette and now we know he is alive and well, though obviously no longer human and that he seems to be part of some elite White Walker group.

It's an insane spoiler because, as far as I recall, the Night's King was just a story. There were many theories about him, and about how his story was relevant to this story, but it's kindof a big deal if it turns out that the Night's King is still around, and this is how it's revealed :p

I was mostly commenting on why it's insane. As a book reader and a show watcher, I had no idea that this could happen. The Night's King stories were always just stories to me, so the fact that he is real and exists within the current timeline, is pretty insane to me.

In the books, we don't really know anything about the White Walkers other than the fact that they seem pretty sentient. Now we know that they have an ice city, an apparent hierarchy, etc... Also, the story of the Night's King is never shown to be real, it's just presented as one of Old Nan's stories. It's now confirmed that not only does the Night's King exist, but he's still alive and will apparently become important for the story.

Just because HBO list him as "The Night's King" does not mean that he is the same Night's King from the stories. Based on the stories, The King in the North and the King Beyond the Wall joined together in successfully killing the original Night's King. I think it is more likely that this is a descendant of the original Night's King. I get that these guys can most likely live forever, but I would say it is more likely that the one we saw in this episode is a Descendant of the first Night's and his White Walker Queen.

At the very least, I tagged him as a leader of the White Walkers. Close enough, really. Whether they consider him king, or commander, doesn't matter to me. Not much of a spoiler, but maybe I'm missing something.

Yeah who knows? I just saw him step forward like he was in charge and he had weird things on his head that looked like a king's crown so I figured he was in charge in some capacity, whatever they want to call him.

He was the 13th Lord Commander of the Night's Watch. He ended up taking an Other (White Walkers in the show) as his queen and generally being a dick until a combined effort by the King in the North and King Beyond the Wall could take him down. Became kind of a boogieman to tell stories about in the North. Shrouded in mystery, and since he lived nearly 7,000 years ago, long presumed to be dead. If that was in fact him at the end of this past episode that's big; in part because Both show and book spoilers

In my experience, having so many tabs open uses up a lot of memory to the point my internet browser crashes and I have to clear up space on my harddrive. Then again, my computer works about as well as a potato, so...

This is the computer equivalent of saying that my car ran out of gas so I changed my Oil to make it work again. Your browser crashes-probably- because of lack of a temporary memory called RAM. It has nothing to do with the permanent storage that is your hard drive. A roughly $300 computer these days has enough ram to keep 50-100 tabs open, so long as they aren't all video or something crazy memory intensive. I routinely have 30-50 open all day at work and that's with a ton of word, outlook, and excel sheets open too, plus usually a music player.
